基础示例代码：启动浏览器

from selenium import webdriver
from selenium.webdriver.chrome.service import Service

# 设置ChromeDriver路径
service = Service('/path/to/chromedriver')
driver = webdriver.Chrome(service=service)

# 打开目标网站
driver.get("https://www.example.com")

# 后续Cookie操作将在此展开...

1. 获取Cookie信息

使用driver.get_cookies()获取所有Cookie：

# 获取所有Cookie
all_cookies = driver.get_cookies()
print("所有Cookie信息：")
for cookie in all_cookies:
    print(f"名称: {cookie['name']}, 值: {cookie['value']}")

# 获取特定Cookie
target_cookie = driver.get_cookie("session_id")
if target_cookie:
    print(f"Session ID值: {target_cookie['value']}")

2. 添加Cookie

使用driver.add_cookie()方法添加Cookie：

# 添加新Cookie
new_cookie = {
    'name': 'user_token',
    'value': 'abc123xyz456',
    'domain': 'example.com',
    'path': '/',
    'secure': True,
    'httpOnly': True,
    'sameSite': 'Lax'
}
driver.add_cookie(new_cookie)

# 验证Cookie是否添加成功
added_cookie = driver.get_cookie("user_token")
print(f"添加的Cookie值: {added_cookie['value']}")

注意： 添加Cookie前必须访问一次目标域名，且domain参数必须与当前域名匹配。

3. 删除Cookie

# 删除指定Cookie
driver.delete_cookie("user_token")

# 删除所有Cookie
driver.delete_all_cookies()
print("已清除所有Cookie")

# 验证删除结果
cookies_after_deletion = driver.get_cookies()
print(f"剩余Cookie数量: {len(cookies_after_deletion)}")

保存和加载Cookie文件

实现Cookie持久化，避免重复登录：

import json
import os

def save_cookies(driver, file_path):
    # 确保目录存在
    os.makedirs(os.path.dirname(file_path), exist_ok=True)
    
    with open(file_path, 'w') as file:
        json.dump(driver.get_cookies(), file)
    print(f"Cookie已保存至: {file_path}")

def load_cookies(driver, file_path, domain):
    # 先访问目标域名
    driver.get(f"https://{domain}")
    driver.delete_all_cookies()
    
    with open(file_path, 'r') as file:
        cookies = json.load(file)
        
    for cookie in cookies:
        # 设置domain属性
        cookie['domain'] = domain
        driver.add_cookie(cookie)
    
    print(f"已从 {file_path} 加载Cookie")
    driver.refresh()  # 刷新页面使Cookie生效

# 使用示例
save_cookies(driver, "./cookies/user_cookies.json")
load_cookies(driver, "./cookies/user_cookies.json", "example.com")

模拟登录状态

使用Cookie绕过登录流程：

# 首次登录并保存Cookie
driver.get("https://example.com/login")
# 执行登录操作...
save_cookies(driver, "./cookies/login_cookies.json")

# 新会话中加载Cookie跳过登录
driver = webdriver.Chrome(service=service)
load_cookies(driver, "./cookies/login_cookies.json", "example.com")
driver.get("https://example.com/dashboard")
# 此时应已处于登录状态
